Which is a cause of drought?
A.High precipitation levels
B.low water demand
C.low precipitation levels
D.high water demand
Drought is the time period where is marked by dry conditions which is caused by the low precipitation levels. Thus, the correct option is C.
What is Drought?Drought is a prolonged dry period in the natural climatic cycle in an environment that can occur any geographic location in the world. It is a slow-onset disaster which is characterized by the lack of precipitation, resulting in a water shortage condition. Drought may cause a serious impact on the overall health, agriculture, economies, energy and the environment of an area.
Drought is mainly caused by a lack of rainfall, which causes serious water shortage. This condition can be fatal. Unlike the other extreme weather events that are more sudden, like that of earthquakes or hurricanes, droughts can happen gradually.
Therefore, the correct option is C.

Answer: An enzyme that copies DNA to make a molecule of RNA is RNA polymerase.
Answer:
RNA polymerase
Explanation:
RNA polymerase has many important roles inside of an organism and is a very complex enzyme. One of the most common roles "RNA polymerases" has, is that it is able to copy DNA to then make an RNA molecule. Another common role the RNA polymerase has, is that it helps maintain the organism's metabolism. Which means the enzyme itself helps the chemical processes within an organism be completed in order to keep that organism from dying.

(WILL GIVE BRAINLIST) A student investigated the effect of root space on plant growth. The student grew two groups of plants of the same variety. Both groups received the same amount of water and sunlight and grew in the same type of soil. The plants in Group A were grown in cube-shaped containers that were 3 centimeters deep. The plants in Group B were grown in cube-shaped containers that were 10 centimeters deep. The table shows the student's observations (picture provided). What was the effect of root space on plant growth based on the student's investigation? Use the data from the table to support your answer. Explain how you would know whether this effect was likely due to environmental or genetic factors.
Answer:
it goes up 2 in the second collum and then plus 1 plus 2 plus 2 plus 4 plus 4
Explanation:
The effect of root space on plant growth is significantly demonstrated by the student who infers that the plants in Group B grown in cube-shaped containers were 10 centimeters deep and obtained high growth as compared to other plants.
What is this growth of root called?Roots grow downward, or towards the center of Earth, and away from light. These responses to external stimuli are called tropisms. Plants' growth response to gravity is known as gravitropism; the growth response to light is phototropism.
The experiment is well-designed and is able to directly infer the effects of root space limitations without having to account for other factors. We can assume that the limited root space will in turn limit the extent to which a plant can grow. This is because plants need larger and deeper roots to support extended growth. Therefore, the plants in group B will grow smaller than those in group A.
Therefore, the effect of root space on plant growth is significantly demonstrated by the student who infers that the plants that have deeper soil will grow high.

Sugars are _____ carbohydrates and starches are _____ carbohydrates
Answer:
sugars are simple and starches are complex.
Explanation:
hope this helps, mr cleann
Sugars are simple carbohydrates and starches are complex carbohydrates.
What are carbohydrates?Sugar molecules make up carbohydrates, or carbs. Carbohydrates are one of the three primary nutrients included in foods and beverages, along with proteins and fats. Glucose is created by your body's breakdown of carbs.
Your body uses carbohydrates as its primary energy source to power your kidneys, heart, brain, muscles, and central nervous system.
As an illustration, fiber is a type of carbohydrate that promotes healthy digestion, makes you feel full, and lowers blood cholesterol levels.
Carbs come in two primary categories: Fructose, glucose, and lactose are examples of simple sugars (or carbs), and they are also present in wholesome whole fruits.
Starchy vegetables, whole grains, rice, breads, and cereals are examples of foods that include complex carbohydrates (also known as starches).
Thus, starches are a type of complex carbohydrate, whereas sugars are a simple carbohydrate.

They are all parasites and reproduce s.ex.ually or as.ex.ually.
They all lack cell specialization and prefer moist environments.
Answer:
d
Explanation:
because i said so lol - trust you will not be sorry
The characteristic that all protista have in common is that they all lack in cell specialization and prefer moist environment. The correct answer is option d.
Protista is a diverse group of eukaryotic organisms that are not classified as plants, animals, or fungi.
There are some common characteristics that are found in many members of this group.One such characteristic is that many Protista are unicellular or colonial, meaning that they are made up of a single cell or a small group of cells.Many Protista have flagella or cilia, which are used for locomotion.Many Protista also reproduce asexually through cell division, although some can reproduce sexually as well.Finally, all Protista live in moist environments, such as freshwater or soil.Therefore, they all lack cell specialization and prefer moist environments. Option d is the correct answer.

In the previous question, you used the Hardy-Weinberg equation to determine the frequencies of the genotypes for HH, Hh, and hh, given gene frequencies of H = 0. 2 and h = 0. 8. These frequencies were: HH = 0. 04 Hh = 0. 32 hh = 0. 64 Now, determine the expected numbers of each organism in the population (total size = 150): Number of HH = Number of Hh = Number of hh =.
The expected number of each organism in the population is HH = 60, Hh = 48, hh = 96.
What is the Hardy-Weinberg equation?The hardy-Weinberg equation is a mathematical equation used to calculate the genetic variation of a population at equilibrium.
The given frequencies are HH = 0.04
Hh = 0.32
hh = 0.64
So, the percentages are HH = 4%, Hh = 32%, hh = 64%.
The total percentage will be (4 + 32 + 64 = 100)
The total size is 150
Now,
The number of HH genotype is 0.4 × 150 = 60
The number of Hh genotype is 0.32 × 150 = 48
The number of hh genotype is 0.64 × 150 = 96
The total is 6 + 48 + 96 = 150
Thus, the expected number of each organism in the population is HH = 60, Hh = 48, hh = 96.
